SPRING. j

Patented July 1, 1919.

Application filed March 17,1919. Serial No. 283,226.

To all whom it may concern:

Be it known that I, J osnrn zen of Austria, residing at Brooklyn, Kingscounty, State of New York,*'have invented certain new and usefulImprovements in Springs, of which the following is a clear, and exactdescription.

This invention relates to improvements in springs, particularly for usein connection with beds to support the apron upon which a mattress islaid. In other Words, my improved spring is especially adapted for usein connection with beds that do not employ the so-called bed-springs orspring-mattresses, but rather an apron which in turn is held orconnected to a bed frame by springs. One of the objects of my inventionis to provide a spring for the purpose set forth that will not collectdirt or vermin. To accomplish the foregoing result, my improved springis formedto obviate corners or surfaces that would collect dirt.

I I will now proceed to describe my invention in detail, the novelfeatures of which will be pointed out in the appended claims, referencebeing had to the accompanying drawing, wherein Figure 1 is adiagrammatic plan view of a form of bed for which my improved spring isespecially adapted;

Fig. 2 is an enlarged perspective view thereof;

Fig. 3 is an enlarged fragmentary perspective view of an alternatemanner of forming one of the loops of the spring, and

Fig. 4: is a perspective view of a modified form of spring.

To accomplish the results set forth, I pre fer to form the spring out ofsuitable material, such as spring wire, wound to form a single coil,said wire being provided with intermeshing or interengaging loopedportions to limit the extensibility of the spring.

Referring to Fig. 2, the spring is formed out of a single strand 5 ofsuitable wire formed into a single coil 6, said coil acting to produceresilient yieldability. To limit the extensibility or contractibility,or in other words, the opening or closing of the 5o coil, I form thewire into loops 7 and 8 which are interengaged or passed one i throughthe other, the loop 8 being a closed a loop produced by securing thatOrtion of the wire which is used to form sai loop 8 to Mnorrz, acitifull, 'or stop, the stop at the opposite end of the the coiledportion 6 thereof, as at 9. The

securement at 9 may be accomplished by spot-welding, wiring orotherwise. To form a closed loop the portion 5 of the strand of wirewill be bent inwardly, as at 10, toward the coiled portion (5 to producean end wall loop being formed by the curved end 11 of loop 8. Theinter-engaging loop 12 is formed by bending the portion 5 of the strand5 to lie in parallelism with the end 5 of said strand, said end 5 beingan extension of the portion 5. The loop 8 will be formed to lie in ahorizontal plane, while loop 12 will be formed to lie in a verticalplane. The outer end of the portions 5 and 5 will be bent to form a hook13. When used in connection with the form of bed hereinbefore mentionedone hook 13 will engage eyes 14 at the end of the apron 15 of the bed,and the other hook 13 will engage eyes 16 in the bedframe 17. It will beapparent that my improved spring will yieldably support the apron 15 andat the same time will be prevented from being broken by being extendedtoo far or opened too much. Should the weight upon the apron besuflicient to open the coil 6 to its utmost extent, the end 11 of loop 8and end 18 of loop 12 would contact one with the other, thereby limitingthe movement of the spring in the direction of the arrows 19 and 20.Such a condition could exist should any considerable weight be droppedon. the mattress of the bed. In this event, the breaking of the springswould be prevented by the stops mentioned. The reaction of snapping backof the coil would be resisted or prevented by the contacting of thestops 10 and 18 of loops 8 and 12 respectively.

By forming a spring in the manner above described, all corners orsurfaces that would collect dirt are obviated, as it will be quiteapparent from an inspection, of Fig. 2, that there will not be anysurface upon which dirt can collect.

Instead of wiring or spot-welding the member 5 to coil 6 as indicated inFig. 2, I may pass said portion 5 through the coil, as indicated in Fig.3, thereby forming the closed loop 8 having the end wall 10.

Fig. 4 illustrates a modified form of my improved spring, in which thestrand of wire is looped as at 21 and 22, said loops being passed onethrough the other, the ends 23 and 24 of the loops 21 and 22,respectively, forming stops.

Having described my invention, What I claim is i 1. A spring consistingWire formed into intermoshing loops, the loops being formed in thatportion of the Wire not employed to form the coil.

2. A spring consisting of a single coil of Wire, that portion of theWire not employed to form the coil being bent overto form interengagingloops, one of saidvloops being closed, the other loop being an openloop.

of a single coil of,

3. A spring consisting of a single coil of ire, said coil at one endterminating in an open loop, the other end of the coil also terminatingin a loop Which engages the loop first named, the-second named loopbeing closed, and means to connect the coiled porday of March, 1919.
